<h2 id="details">Detailed Description</h2>
<p>A widget must accept this event in order to receive the <a href="qdragmoveevent.html">drag move events</a> that are sent while the drag and drop action is in progress. The drag enter event is always immediately followed by a drag move event.</p>
<p>QDragEnterEvent inherits most of its functionality from <a href="qdragmoveevent.html">QDragMoveEvent</a>, which in turn inherits most of its functionality from <a href="qdropevent.html">QDropEvent</a>.</p>

<p>Constructs a QDragEnterEvent that represents a drag entering a widget at the given <i>point</i> with mouse and keyboard states specified by <i>buttons</i> and <i>modifiers</i>.</p>
<p>The drag data is passed as MIME-encoded information in <i>data</i>, and the specified <i>actions</i> describe the possible types of drag and drop operation that can be performed.</p>
<p><b>Warning:</b> Do not create a QDragEnterEvent yourself since these objects rely on Qt's internal state.</p>
